Prosecutors invoke 18th-century All Writs Act to get around thorny problem.

OAKLAND, CA—Newly discovered court documents from two federal criminal cases in New York and California that remain otherwise sealed suggest that the Department of Justice (DOJ) is pursuing an unusual legal strategy to compel cellphone makers to assist investigations.

In both cases, the seized phones—one of which is an iPhone 5S—are encrypted and cannot be cracked by federal authorities. Prosecutors have now invoked the All Writs Act, an 18th-century federal law that simply allows courts to issue a writ, or order, which compels a person or company to do something.

Some legal experts are concerned that these rarely made public examples of the lengths the government is willing to go in defeating encrypted phones raise new questions as to how far the government can compel a private company to aid a criminal investigation.

Two federal judges agree that the phone manufacturer in each case—one of which remains sealed, one of which is definitively Apple—should provide aid to the government.

Ars is publishing the documents in the California case for the first time in which a federal judge in Oakland specifically notes that "Apple is not required to attempt to decrypt, or otherwise enable law enforcement’s attempts to access any encrypted data."

The two orders were both handed down on October 31, 2014, about six weeks after Apple announced that it would be expanding encryption under iOS 8, which aims to render such a data handover to law enforcement useless. Last month, The Wall Street Journalreported that DOJ officials told Apple that it was "marketing to criminals" and that "a child will die" because of Apple’s security design choices.

Apple did not immediately respond to Ars’ request for comment.

Meet the “All Writs Act”

Alex Abdo, an attorney with the American Civil Liberties Union, wondered if the government could invoke the All Writs Act to "compel Master Lock to come to your house and break [a physical lock] open."

"That's kind of like the question of could the government compel your laptop maker to unlock your disk encryption?" he said. "And I think those are very complicated questions, and if so, then that's complicated constitutional questions whether the government can conscript them to be their agents. Then there's one further question: can the government use the All Writs Act to compel the installation of backdoors?"

But, if Apple really can’t decrypt the phone as it claims, the point is moot.

"Then that’s pretty much the end of it," Hanni Fakhoury, a staff attorney at the Electronic Frontier Foundation, told Ars. "The writ doesn’t require Apple to do something that is impossible for it to do."

Thus, as far as I can tell, the government proposes that I use the All Writs Act in an entirely unprecedented way. To appreciate just how unprecedented the argument is, it is necessary to recognize that the government need only run this Hail Mary play if its arguments under the electronic surveillance and disclosure statutes fail.

…

The government thus asks me to read into the All Writs Act an empowerment of the judiciary to grant the executive branch authority to use investigative techniques either explicitly denied it by the legislative branch, or at a minimum omitted from a far-reaching and detailed statutory scheme that has received the legislature's intensive and repeated consideration. Such a broad reading of the statute invites an exercise of judicial activism that is breathtaking in its scope and fundamentally inconsistent with my understanding of the extent of my authority.

“Any capabilities [Apple] may have to unlock the iPhone”

One of the new phone search cases was filed in federal court in Oakland, just across the bay from San Francisco, while another was filed in federal court in Manhattan.

"This Court has the authority to order Apple, Inc., to use any capabilities it may have to unlock the iPhone," Garth Hire, an assistant US attorney, wrote to the court and cited the All Writs Act.

"The government is aware, and can represent, that in other cases, courts have ordered the unlocking of an iPhone under this authority," he wrote. "Additionally, Apple has routinely complied with such orders."

"This court should issue the order because doing so would enable agents to comply with this Court’s warrant commanding that the iPhone be examined for evidence identified by the warrant," he continued. "Examination of the iPhone without Apple’s assistance, if it is possible at all, would require significant resources and may harm the iPhone. Moreover, the order is not likely to place any unreasonable burden on Apple."

In response, Magistrate Judge Kandis Westmore ordered that Apple "provide reasonable technical assistance to enable law enforcement agents to obtain access to unencrypted data." She did not specifically mention the All Writs Act.

But she added:

It is further ordered that, to the extent that data on the iOS device is encrypted, Apple may provide a copy of the encrypted data to law enforcement but Apple is not required to attempt to decrypt, or otherwise enable law enforcement’s attempts to access any encrypted data.

Westmore’s language is a near-duplicate of a June 6, 2014 order issued by a different judge from the Northern California district, San Jose division, which is about 40 miles south of Oakland. There, Magistrate Judge Howard Lloyd ordered Apple to assist in the search of an iPad Mini, months before the release of iOS 8.

New spying tools afoot

On Tuesday, The Wall Street Journal reported on an order issued by a federal magistrate in New York in a case involving alleged credit card fraud.

The mystery company could challenge the judge’s order, according to Brian Owsley, a former federal magistrate judge who now is a law professor at Indiana Tech.

"Unfortunately, we will probably not know because the issue will likely be sealed even though there should be more transparency in these issues," he told Ars by e-mail, noting that during his tenure on the bench he could not remember a time when the government invoked the All Writs Act.

"It is only through greater transparency will we start to get the answers. If the provider simply complies we will know nothing. Here, Judge Gorenstein's approach strikes me as very even-handed, but the inherent problem is that those who are concerned about privacy issues in general simply have to hope that the provider will speak up for us."

But Orin Kerr, a law professor at George Washington University and a former federal prosecutor, does not believe that the seized phone in the New York case was an iOS 8 device.

"The government obtained a warrant on October 10 for a phone already in its possession," he told Ars by e-mail. "Apple's announcement was something like September 18. If it was an iPhone, it was probably an iPhone running [on] an earlier operating system."

Still, Alex Abdo, the ACLU attorney, after reading a copy of the Oakland documents, concluded that the "government’s application raises troubling questions about the extent to which it can force companies to break the products they sell."

"We are heartened, however, that the court recognized that possibility and stopped short of ordering Apple to come up with a way to decrypt its customers’ data," he added.

"More broadly, it is disconcerting that the government is relying on a catch-all law to seek surveillance powers that it should be seeking from Congress and the public," said Abdo. "If the government wants new spying tools, it should allow our democratic process to debate them openly first."

"The TL;DR is that there is nothing new about using the All Writs Act to compel assistance," Mayer told Ars by e-mail. "And there is also nothing new about using it to compel assistance with unlocking a phone. That repeated language you saw? It's provided by Apple itself!"

"As for the opinion discounting the All Writs Act, that had to do with surveillance under the Electronic Communications Privacy Act. Where ECPA applies, the All Writs Act doesn't. (It's just a default, as the court rightly noted.) Phone unlocking isn't covered by ECPA, so the All Writs Act remains in play."
